Saint Gregory was born at Nazianzus in Cappadocia (Editor: Modern-day Turkey). He was educated at Athens in all the sciences, at the same time as Saint Basil the Great, with whom he was always united in the bonds of a holy friendship. Brothers in their studies, they remained brothers in their Monastic life and in the Episcopate.

Having become Bishop of Nazianzus, and, later, Patriarch of Constantinople (Communion), he was "the light which, raised on the candlestick, sheds its rays on all those who dwell in the house" (Gospel).

Filled with "the spirit of Wisdom and Intelligence" (Introit, Epistle), his profound knowledge of The Scriptures earned for him the Title of Doctor and Theologian, which The Church has confirmed. Saint Gregory Nazianzen died in 389 A.D.
